DOUBLE GEAR FOR CARTS.

SPECIFICATION forming part of Letters Patent No.-789,090, dated May 2, 1905.

Application filed December 3, 1904. Serial No. 235,284.

T all whom t may concern.-

Be it known that I, DANIEL GIBERsoN, a citizen of the United States, residing at Wilmington, county of Newcastle, and State of Delaware, have invented a certain new and useful Improvement in Double Gear for Carts, of which the following is a specification.

My invention relates to a new and useful improvement in double gear for two-wheelv carts, and has for its object to provide means whereby two horses may be utilized to draw a two-wheel cart, each horse to sustain onehalf of the amount of the Weight of the cart.

A further object of my invention is to so construct the apparatus that it will be extremely simple, comparatively cheap in construction, but at the same time will be extremely efiicient and durable in action.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a cross-section through the tongue of a cart, showing my improvement a plied thereto; Fig. 2, a section taken on the ine 2 2 of Fig. 1.

A represents the tongue of the cart, which is adapted to be secured to the running-gear of the cart rigidly, the same as the shafts are now secured.

B is a bar extending parallel with the tongue A underneath the same for a short distance, and C is a similar bar extending parallel with the tongue A above the same directly over and the same length as the bar B.

D is a link the upper end of which is adapted to slide upon the bar B, and the lower end of said link is secured rigidly to the cross-bar E which extends each side of the tongue and adapted to pass underneath the body of the A horses, and to each outer end of the cross-bar E are secured hooks E.

F is a block adapted to slide upon the upper bar O, and this block carries a ring F into which is adapted to be hooked hooks G, to which hooks is secured one end of each yoke H. These yoke-chains are adapted to pass over the saddle upon the harness of the horses, one over one horse and the other over the other horse, and to the other end of these yoke-chains are secured the hooks I, which are adapted to be secured to the hooks E upon the end of the cross-bar E. Thus it will be seen that the yoke-chains H will bear the weight that is put upon the tongue E, and two horses can thus be utilized to pull a two-wheel cart, each horse sharing the weight and at the same time pulling evenly upon the cart, and when it is desired to unharness the horses the yoke-chains H can be easily and uickly disengaged to allow the tongue A to rop, and when the horses are unlfastened from the cart they can easily step over the cross-bar E.

While I have shown the hooks G and I in the drawings as simple ring-hooks, it is obvious that any other form of hook may be used, such as a snap-hook or the like, which can be easily and quickly disengaged, but will hold securel while in use.

J re resents ooks secured to the outer ends o the cross-bar E, to which extra quilerstraps may be secured to hold the cross-bar in position and hold it even if one horse should travel ahead of the other.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is--v In a device of the character described, a tongue, a bar extending longitudinally of the tongue a short distance below the same, a bar extending longitudinally of the tongue a short distance above the same7 alink adaptthe sliding block, as and for the purpose ed to slide upon the lower bar, a cross-bar sespeoed. cured to the lower end of the link, :a block In testimony whereof I have lhereunto af- `sldably secured upon the upper bar, tWo Xed mysignature n the presence of two subyoke-ehains, one end of one yoke-chain resoribng Witnesses.

movably secured to one end of the Gross-bar, DANIEL GIBERSON. one end of the other chain removably se- Witnesses: cured to the' other end of the cross-bar, the WILLIAM H. GIBBoNs,

other end ofthe chain removably securedv to SAMUEL H. DURs'rEIN.
